Defined a named region on a mesh that will have associated triangles and bones for fast sampling at each enabled LOD.
struct FSkeletalMeshSamplingRegion
TArray<FSkelet...
BoneFilters
Filters to determine which triangles and bones to include in this region based on bone.
uint32:  1
bSupportUniformlyDistributedSampling
Mesh supports uniformly distributed sampling in constant time. Memory cost is 8 bytes per triangle.
int32
LODIndex
The LOD of the mesh that this region applies to.
TArray<FSkelet...
MaterialFilters
Filters to determine which triangles to include in this region based on material.
FName
Name
Name of this region that users will reference.
